Gang of Four

Foreign trade in 1976 was weakened by the death of China s three leaders, Chairman Mao Tse-tung, Premier Chou En-lai and Chu De, father of the People s Liberation Army, and continuing low foreign trade statistics reflected the miseries of the Chinese people, who at that time brought about, and suffered from, serious production and transportation difficulties. These were incited, as the Chinese like to say, by the oppressions of the infamous "Gang of Four". 

In 1976, the Gang of Four was crushed, when it was perceived that Chairman Mao s last years were being orchestrated by the oppressive and exploitive Gang, carrying on the repressions of the Cultural Revolution for their own purposes. 

ZSM-5 is the latest member of the gang of four zeolites to have reached large-scale commercial application. It is also one of the most versatile zeolites in its synthesis it can be made with very different Si/T (T = Al, Fe, B, Ga, Ti,...) ratios, particle sizes and shapes, synthesized in the presence of either organic or inorganic cations, combinations of these, anionic surfactants [47], etc. Patent and journal literature abounds on ZSM-5 [48, 49], but only few authors [17, 37, 43, 50] have tri to describe the ZSM-5 synthesis on a molecular basis and Shell researchers introduced the D5R as the key building block of ZSM-5, Figure 14. 

Regionwide combines were formed up and down the East Coast for smooth distribution. The Reinfeld Syndicate — named after the Newark, New Jersey bootlegger and accused murderer Joseph Reinfeld — functioned as the middleman between the British liquor distilleries and the "Rum Rows" of Boston and New York. Its controlling shareholders were the four Bronfman brothers, Allan, Sam, Edgar, and Charles. The U.S. leg was handled by Reinfeld and Abner "Longie" Zwillman, later the boss of Atlantic City, and Rothstein s gangs in New York. (9)... 

To obtain adequate reactivity control of the reactor for the seous UF experiment, these rotary control elements were replaced by linear boron vanes running vertically, which could be inserted into the beryllium reflector from the top and acted as a reactivity poison on insertion. Eight such vanes were provided four could be individually controlled for reactivity measurements and four ganged together and were controllied by ah air-driven solenoid to act as safeties in case of a scram shutdown. Each of these vanes was worth about 2S, so the total shutdown from the four safeties alone was nearly. 8. Since our operating plan demands two independent safety, scram mechanisms, the ram drop was also used as an additional scram independent of flie boron safety vanes. 

The speed and capacity of the RC I function permit the control of more than one rod at a time. Up to four rods can be operafed simultaneously. The position of each rod in a gang is monitored. 

The sample moves by a scanner under a fixed probe.The probe consists of a silicon nitride tip attached to a cantilever, which can move up and down. A laser beam is reflected from the back of the cantilever to a photodiode divided into four segments (quadrant photodiode). As the cantilever bends up and down (or left and right) from surface forces acting on the probe tip,it deflects the laser beam to different quadrants of the photodiode. A computer coordinates the output from the photodiode with the sample position to create an image that appears on the computer screen.

Control computer programming shall be developed to collect the control rod gang demand data, the four high level flux monitor (HLFM) meter readings, and the 2 Log-N meter readings and to transfer these data to an off-line computer. (DB-3.5 of K-Reactor Restart Strategy.)...
